Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Learners explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Learners plasma membranes, solutes and organelles.

Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...

Students explore the amount of lead in ceramic plates through an experiment. Students determine if everyday dishware is leaching lead into food. They chart their results and discuss how much lead in ceramic dishware may cause lead...

Students investigate DNA Fingerprinting techniques and applications. They participate in a scenario to analyze blood to discover who shattered a plexiglass backboards. In addition, they explain why the DNA fingerprint of blood from the...

Twelfth graders examine protein shapes through a computer program that can be downloaded off the Internet. The program allows students to see how proteins look when viewed with X-ray crystallography.

Learners explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.

Students define biotechnology and discuss the economic impact of biotechnology. They also describe what a 1015 onion and a slow-softening tomato are and how they are produced. They examine the safety of genetically-engineered or altered...

Students examine diversity on the planet and the differences within a species.  In this investigative lesson students complete a lab that allows students to better understand the relatedness between plants. 

Students examine protein, what it is and how it functions in the body.  In this protein instructional activity students study the food pyramid, what a protein is and what it does. 

Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.

High schoolers compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared...

Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.

The discovery of restriction enzymes and their applications in DNA analysis has proven to be essential for biologists and chemists. This lesson focuses on restriction enzymes and their applications to DNA analysis and DNA fingerprinting....

For this science activity, you will investigate the enzyme called catalase to find out how it helps to protect your body from cell damage.

In this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.

By using inquiry skills, students will design and complete a lab investigation to gain an understanding of the concept of enzymes.

In this biology simulation, students discover what factors influence the action of enzymes on cellular work. Students will first explore the action of enzymes through a simulation in which their hands are the enzyme "toothpickase" and...

Students are introduced to the latest imaging methods used to visualize molecular structures and the method of electrophoresis that is used to identify and compare genetic code (DNA). Students should already have basic knowledge of...

Learners learn the fundamentals of using microbes to treat wastewater. They discover how wastewater is generated and its primary constituents. Microbial metabolism, enzymes and bioreactors are explored to fully understand the primary...

Lesson explores scientific principles in using eggs as a highly nutritious and versatile food source of protein.
